水平集的快速行进方法,是一种水平集的求解方法,对研究水平集的朋友很有用(This is a method of level set,adopting fast marching. It is very usefull to everyone.)

文件夹“AWGN”说明了系统误码率在均衡前后随SNR增加的变化。 （1）绘制误码率曲线。运行m文件：main_picture,调用主函数：ofdm_AWGN。 （2）绘制星座点图。运行m文件：snr_xinzuotu(Folder )

说明：  图像置乱，图像处理MatLab程序，适合于中高级用户。(images, image processing MatLab procedures, suitable for senior users.)

微波滤波器耦合矩阵综合， 1 根据传输零点位置，回波损耗求出耦合矩阵； 2 从S21 S11多项式出发 综合出耦合矩阵； 3 已知传输零点位置，滤波器阶数，回波损耗画出滤波器的S参数，分别以4阶和八阶滤波器为例。(1synthesize coupling matrix by the transmission zeros, return loss 2 synthesize coupling matrix by S21 S11 polynomial 3 draw the S parameters of the filter by transmission zeros, return loss,order of filter, Using 4 order and 8 order filter respectively as an example.)

LMS滤波，自适应滤波法，试过了，可以用(LMS filter, adaptive filtering, tried, you can use)

说明：  这是一本关于matlab的教程，同时也是一本信号处理的教程，其特点是将matlab用于信号处理(This is a tutorial on matlab, but also a signal processing tutorial, and its characteristic is used in signal processing matlab)

去趋势波动分析的开发程序，共享给大家，谢谢。(Detrended fluctuation analysis of the development process, for everyone to share, thank you.)

船舶路径跟纵，只限跟踪，contro微控制器，vlm为船模型(line path following)

对于高斯脉冲信号，在光纤传输过程中需要考虑群速度色散和交叉相位调制(For the Gaussian pulse signal, in the optical fiber transmission process need to consider the group velocity dispersion and cross phase modulation)

用矩阵撕裂法，多次用matlab运算，得出复杂系统的15个节点的电压(Tear voltage matrix method, repeatedly using matlab computing, complex systems derived 15 nodes)
